Android VideoView的奇怪行为 - "无法播放视频"

MKJ*_*ekh 24 android android-videoview

在我的应用程序中,通过传递所选视频的文件路径,在不同活动的VideoView中显示来自sdcard文件夹的视频或来自Video intent的新视频.

现在的问题是,我已经在我的2个设备中测试了这个应用程序,LG Optimus Black and LG Optimus Me and it works如魅力没有问题没有力关闭.

现在当我测试这个应用程序时,Samsung Fascinate 2.1 the video view shows the message "Can't Play Video"无论我选择现有视频还是采用新视频.

请记住,该应用程序与上述2个设备正常工作.

在ShowVideo活动中,我有按钮上传视频,当我收到消息"无法播放视频"时,我能够从同一路径拍摄视频并上传它并可以在服务器端检查该视频,但视频视图没有播放那个视频.

So, the Video Path of the SDCard is not the problem thats for sure.

also the Video are of .3gp or .mp4 format only so the format is also supported by android

我的问题是:

1)当出现"无法播放视频"消息时？2)有什么解决方案？3)我的申请中可能出现的错误是什么？

这是logcat输出,当我收到该消息但没有看到任何错误/异常.

如果您发现任何未描述的内容,请在下面评论.

其他细节(从评论中移除):

  • 它们仅仅是1分钟而且是我测试的最后一个并且在三星上失败只有20秒.和大小目前大多以MB不超过20 MB.
  • 该视频是从同一台设备上拍摄的,拍摄完该视频后,我尝试以同样的方式显示其他已存储的视频也很好...实际上,在上传该视频后,我可以看到该视频,也可以下载

1)当出现"无法播放视频"消息时？

当Android无法播放媒体内容时,Android通常会发出此消息.发生这种情况的原因可能就是这样

  • 不支持的文件格式
  • 不受支持的编解码器
  • 错误的内容

提一些.

2)有什么解决方案？

除非您的应用程序中有自己的Media Framework,否则应用程序级别没有解决方案

3)我的申请中可能出现的错误是什么？

你的申请中的错误很不可能发生.如果您阅读日志,您会看到错误似乎来自opencore的DataSource(您运行的是哪个版本的Android？它仍然使用Opencore而不是StageFright).它将其识别为一个大文件(> 2GB),因此发出错误" E/OsclDirectFileIO(2182):[LargeFileSupport] OsclDirectFileIO :: OpenFileOrSharedFd Error = -1 "

另外需要注意的是,某些手机具有比其他手机更好的多媒体功能,因为OEM可以自己提高多媒体功能.因此,没有书面保证所有文件都可以在所有设备上播放,即使它符合Android提到的支持格式,编解码器.

  • 你的意思是应用开发者？然后不,他无能为力. (7认同)
